Where are the radiation protection stickers for mobile phones?
First of all, you need to know what kind of mobile phone anti-radiation sticker is, and different anti-radiation stickers have different sticking methods.
1. If it is metal foil, it depends on the principle of shielding. Generally, it is attached to the antenna on the back of the mobile phone (that is, the back of the handset) or the battery cover.
2. If it is the pulse clean series imported from Japan, such as 9000A, 5000A, 20000A, by releasing negative ions to neutralize the positive ions in the electromagnetic radiation, the radiation protection stickers can be attached to the front and back of the mobile phone or on the jacket.
Are radiation protection mobile phone stickers useful?
Mobile phone anti-radiation stickers, also known as mobile phone anti-magnetic stickers, mobile phone shielding film. The principle is to neutralize the positive ions generated by the electromagnetic waves of the mobile phone through the negative ions released by the tourmaline. The main purpose is to reduce the impact of mobile phone radiation on the human body.
However, some experts said that the radiation of mobile phones is mainly electromagnetic wave radiation. When the phone is connected, parts such as the receiver or antenna will exist to varying degrees. It is unlikely that only a simple paste is used to absorb and screen radiation. An effective way to reduce mobile phone radiation in daily life is to use earphones to answer the phone and try to avoid close contact with the human body.
How to effectively prevent mobile phone radiation
1. The moment when the mobile phone is turned on and the few seconds before and after the mobile phone is connected is the time when the electromagnetic radiation of the mobile phone is the strongest. Therefore, during these two time periods, it is best not to let the phone close to your body, or to listen to the ear.
2. When you feel that the head or face that is answering the phone starts to heat up, stop calling immediately, and scrub and massage your face with hot water to promote the recovery of the injured tissue.
3. Minimize the time spent on mobile phone calls, and don't "talk on the phone". If a call time really needs to be longer, you might as well stop for a while and divide it into two or three conversations. Since the thermal effect of radiant energy is an accumulation process, the time of each use of the mobile phone and the number of times of using the mobile phone per day should be minimized. When it is necessary to talk for a long time, it is more scientific to use the left and right ears alternately.
4. It is recommended to use the headset for those who often use mobile phones and talk for a long time. The main effect of mobile phone radiation on the head is near-field radiation. When the mobile phone is more than 30cm away from the head, the radiation to the head will be greatly attenuated. Tests conducted by China's Taier Laboratory have shown that under normal circumstances, the use of earphones is more than 100 times smaller than the radiation received by the head of a mobile phone. Especially for those people who are sensitive to mobile phone radiation, the use of earphones will eliminate the user's subjective symptoms.
5. Do not hang your phone around your neck or waist. The radiation range of the mobile phone is a ring-shaped belt centered on the mobile phone, and the distance between the mobile phone and the human body determines the degree to which the radiation is absorbed by the human body. Therefore, people need to keep their distance from mobile phones. Some medical experts have pointed out that people with heart insufficiency and arrhythmias should not hang their mobile phones on their chests. If the mobile phone is often hung on the waist or abdomen of the human body, it may affect fertility. A healthier and safer way is to put your mobile phone in your carry-on bag and try to put it on the outer layer of the bag to ensure good signal coverage.
